This AOP was created by ANecessaryEvil (Dale Matteson) in November 2010.
The brushes were created using the alphabet and numbers 0-9 that have 3D shading.
As you can see from the sample images this AOP can be used on many different types of images. One of the main things to be aware of when using it is how the Outline setting is set. This can make a great difference in how clean the image looks.
